Form That Flexes Beyond Today
Engineered to support any NVMe M.2 2280 SSD and any 3.5" SATA HDD, this compact powerhouse gives you the ultimate flexibility to choose the drive configuration you want today—including blazing fast highly reliable OWC Aura SSDs with up to a massive 8TB capacity. When tomorrow’s 16TB and larger NVMe SSDs hit the scene, you can easily boost your StudioStack’s capacity.

Lift Beyond Your Limit
With StudioStack’s three Thunderbolt 5 and three USB-A ports, you’ll lift the connectivity limit of your Mac mini M1/M2 machine to a new PR. You’ll also love how easy and fast the two side-located USB-A ports make plugging in flash drives, card readers, and other frequently used devices instead of blindly fumbling around behind your machine.

Your Data’s Reliability is Our #1 Priority
Like all OWC storage products, StudioStack underwent rigorous development testing processes, including intensive mandatory Thunderbolt certification. This hyper-focused attention to detail helps ensure you’ll enjoy a guaranteed consistent experience using StudioStack with a wide range of products and brands. As a final quality assurance, every StudioStack solution goes through a multi-step performance verification prior to shipping.
While the priority for some storage devices is to be a mass-produced, lowest price commodity, we do things differently because the reliability of your data and the longevity of an OWC product is priority #1.
